Very recently, the LHCb Collaboration reported a fully charmed tetraquark state $X(6900)$ in invariant mass spectrum of $J/\ensuremath{\psi}$ pairs. If one meson is replaced with baryon, we obtain pentaquark candidate. In this work, perform systematic study on spectra $S$-wave heavy $QQQQ\overline{Q}$ framework chromomagnetic interaction model. Based our results two different schemes, further i...
